     * Editor features may introduce more configuration options that can be set through this parameter.
     * @param options.rootName Root name. Default to `'main'`.
     * @param options.trim Whether returned data should be trimmed. This option is set to `'empty'` by default,
     * which means that whenever editor content is considered empty, an empty string is returned. To turn off trimming
     * use `'none'`. In such cases exact content will be returned (for example `'<p>&nbsp;</p>'` for an empty editor).
